Tempo On-Chain AML & Travel Rule Screener

Parses a batch of synthetic TIP-20 transfers (with 32-byte memos), runs OFAC/SDN screening against a hardcoded test watchlist, applies FATF Travel Rule field-completeness checks (originator/beneficiary name, VASP ID, value threshold), scores AML typologies (structuring, layering, missing identity), and emits a SAR determination + Travel Rule attestation. Tempo mainnet launched March 18, 2026, incubated by Stripe & Paradigm.
